Product Description
High-Performance Bentonite Geosynthetic Clay Liner
Advanced sodium bentonite waterproof blanket (GCL) engineered for superior waterproofing and impermeability in environmental and civil engineering applications.
Key Product Properties
- Excellent Waterproof Performance: Sodium bentonite absorbs water equivalent to several times its own weight, expanding to form an impermeable gel barrier
- Low Permeability: Permeability coefficient typically below 1×10⁻⁹ cm/s for long-term reliable waterproofing
- Versatile Applications: Functions as geosynthetic material for reinforcement, isolation, and filtration in geoengineering
- Cost-Effective Solution: Higher cost performance compared to alternative waterproof materials
Primary Applications
- Environmental Engineering: Base treatment and capping for waste landfills with superior sealing and leak prevention
- Water Conservancy Projects: Underground reservoirs, channels, and river projects for enhanced structural stability
- Civil Engineering: Waterproof layer for basements, subways, tunnels, and underground passages
Standard Specifications
- Unit Weight: ≥4000 g/m² (customization available)
- Width: 4-6 meters
- Roll Length: Custom lengths available upon request
